Patent CA-2367420-A1 (CA)
Title: Method for inserting a watermark into an image
Inventor: NICHOLSON DIDIER
IPC: H04N7/26
Filed: 2000-04-07
Abstract: A process for watermarking images that includes embedding into the images before their transmission a message by modifying the data characteristic of the images. Further, a co-watermarking is performed by periodic embedding of a binary matrix into the image to determine on reception the co-ordinates of the origin of the initial image and allow the registration of the images received relative to this origin so as to make it possible to read the embedded message. Such a process may find particular application to the transmission of stationary or video images.

Patent CA-2370256-A1 (CA)
Inventor: CONNER JEFFREY ALLEN
IPC: C23C4/02
Filed: 2002-01-31
Abstract: A method is provided for refurbishing a service operated metallic coating (12) on a substrate alloy (10), the coating (12) including at least within a coating outer surface (16) at least one oxide (14) chemically grown from at least one coating element, for example Al, and chemically bonded with the coating outer surface (16) as a result of thermal exposure during service operation. Growth of the oxide (14) has depleted at least a portion of the coating element from the coating (12). The method comprises removing the oxide (14) from the coating outer surface (16) while substantially retaining the metallic coating (12), thereby exposing in the coating outer surface (16) at least one surface void (18) that had been occupied by the oxide ( 14). The retained metallic coating (12) is mechanically worked, substantially without removal of the retained coating (12), to close the void (18), providing a treated metallic coating surface (20) over which a refurbishing coating (22) is applied. In one form, the mechanical working provides, concurrently, a compressive stress in the substrate alloy (10) beneath the metallic coating (12).

Abstract: In a disk drive (2), a disk drive controller circuit (15) and method keep track of defective and/or undesired sectors on a disk (25), and skip such sectors during a read or a write operation requested by a host system (5). A microprocessor (20) is programmed to respond to a read or write command from the host system (5) by converting a list of sectors to be skipped to an address and range format suitable for loading a set of registers (105) within the controller circuit (15). The microprocessor (20) loads the set of registers (105), and the controller circuit compares each sector identified by the read or write command with the contents of the set of registers (105). If a sector identified by the read or write command matches one of the sectors to be skipped, the controller circuit skips that sector during the read or write operation.

Title: Leak proof pressure relief valve for secondary batteries
Inventor: PHILLIPS JEFFREY
IPC: H01M2/12
Filed: 2002-03-15
Abstract: Secondary batteries are subjected to power cycling, and those which have a liquid electrolyte within the interior volume are equipped with a pressure relief valve. A void space over the liquid electrolyte may be subjected to gas pressure variations with respect to the ambient. The pressure relief valve structure comprises a vertically oriented gas flow chamber, and an outer relief vent adapted to open only when gas pressure within the battery and the gas flow chamber exceeds a predetermined pressure with respect to the ambient pressure. The gas flow chamber extends below the top surface of the battery, and has a dome-like cap which extends downwardly and has a plurality of openings so as to permit unimpeded gas flow between the interior of the battery and the gas flow chamber. There is a porous membrane covering the dome which permits gas flow between the interior of the battery and the gas flow chamber, but precludes flow of liquid electrolyte from the interior volume of the battery to the gas flow chamber.
